I have a Moto G2 running on lollipop. For some reason, the cast screen functionality is disabled in this. I would really like to get a work around on this. I know that we can add persist.debug.wdf.enable=1 in build.prop, it may work. Now the question is If we can add this line, WITHOUT ROOTING. Any help will be appreciated and pls do keep in mind that I'm a novice to this whole thing.
